Product Description

The Vibrant Performance 2745 90° Silicone Elbow Coupler is a robust universal connector designed for custom intake, turbo, intercooler, and coolant plumbing applications where a tight bend is required. Built with a 4-ply aramid-reinforced silicone construction, this elbow resists swelling or bursting under high-pressure conditions and provides reliable performance across a wide operating temperature range from approximately -65 °F to 350 °F.

With a 3.50" inside diameter and equal leg lengths, this elbow is ideal for linking boost piping in congested engine bays - such as routing around chassis components, connecting turbo compressor outlets to intercooler pipes, or joining charge-air lines. The reinforced silicone design ensures durability in street, performance, and track builds. Because it's a universal coupler, it isn't tied to any specific vehicle - fitment is determined by matching the 3.5" size to your custom piping needs.
